Study on Roof‐Control Technology for Gob‐Side Entry Retaining Under Composite Roofs

Energy Science &Engineering, EarlyView.
This study develops a roof‐control technology system for gob‐side entry retaining under composite roofs. By integrating field measurements, theoretical analysis, and numerical simulation, it reveals the spatiotemporal evolution of the plastic zone and proposes a targeted support method, providing theoretical and practical guidance for safe and ...

Score Reliability and Validity of a Mexican Dialect Spanish Translation of the Flourishing Scale With Mexican Earthquake Survivors

Journal of Counseling &Development, EarlyView.
ABSTRACT The Flourishing Scale (FS) scores have demonstrated acceptable psychometric properties in general adult populations, but no previous research has validated its use among natural disaster survivors. This study examined the reliability, validity, and measurement invariance of a Mexican dialect Spanish translation of the FS in 289 Mexican ...

Revealing the Resonant Physics of Open Photonic Time Crystals

Laser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Ladder fuels rather than canopy volumes consistently predict wildfire severity even in extreme topographic-weather conditions

Communications Earth & Environment
Drivers of forest wildfire severity include fuels, topography and weather. However, because only fuels can be actively managed, quantifying their effects on severity has become an urgent research priority.

Environmental factors related to entry into and ascent of fish in the experimental ladder located close to Itaipu Dam

Neotropical Ichthyology
We evaluated the seasonality of the ascent of fish in an experimental ladder located close to Itaipu Dam, and its relationships to reproduction, temperature, river level and discharge.

Ladder-Type Polymers and Ladder-Type Polyelectrolytes with On-Chain Dibenz[a,h]anthracene Chromophores

, 2019
The alternating copolymerization of fluorene and diethynyl benzene building blocks and postpolymerization electrophilic cyclization result in the generation of well-defined ladder poly­(dibenz­[a,h]­anthracene)­s (PLDBAs).

Allocation of Indivisible Items With a Common Preference Graph: Minimizing Total Dissatisfaction

Networks, EarlyView.
ABSTRACT Allocating indivisible items among a set of agents is a frequently studied discrete optimization problem. In the setting considered in this work, the agents' preferences over the items are assumed to be identical. We consider a very recent measure for the overall quality of an allocation which does not rely on numerical valuations of the items.

Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

Journal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.
